See the other posts on the forum via search, but short answer is you use Notepad to edit the usercfg.opt file to turn on that feature and set it to Ultra. Very easy to do and it works well. When you open that file you scroll down and find that setting and put in a 1 to replace the 0 to activate the caching, then you set it to 3 from default 1 which means ultra as opposed to the default of medium. Save and close the file and relaunch the sim. This missing menu option will be added back in the upcoming hot fix announced yesterday as well.
